`In the drawings the'nuxneral "I designates an automobile seat having a back rest 2. Attached to thebottom ofthe seat are two slides 3. formed formed with substantially horizontal portions 22 Fig. ,a is` a1 `plan vof `.the e slide ,assembly with the t :their pivots 2l.

ofsneet metal, and beingof` channel "shape More specifically, the slides 3 `whenxviewedfin "cross section-.comprise two parallel side. walls 4 in the slides arelrollers -II and I2. .e The rollers `Il are located adjacent tothe rear ends `or" theiry e respective slides and the' rollers I2 are-located at points spaced Ainwardly from `the forward ends of thefslides. g A i Pivotallyattachedkto brackets I3. which are `rigidly secured to the oor I4 of the vehicle are guide membersK I5.` The guide members l are formed of two stamped parts I6 which are welded e togetheneaoh of the parts I6 having an outwardly `extending flange I1. The anges I1 terminate at "a Vpoint spaced lfrom the `forward endsof the `parts I6` wherebyv to `provide asurplus 'of metal which extends upwardly to providestops or abute ments I8, and the parts .lhave depending ears j I9 freiniorcedlby inserts 20 for thereception of pins 2| `which secure the parts I6 to the brackets The upper surfacesfof the flanges I'I are extendingfrearwardly fromjthe forward ends thereof and with downwardly inclinedfportions 23 extending from the portions 22 to the rear ends i thereof.` The rear endslof the parts 1I6 are spaced 4apart for the reception ofbrackets 24 and` the. two

" brackets are unitedbya rigid web25. Each bracket 24 has an integral upwardlyextndingl portion providing a stopor abutment. e f Whenthe partsof `the above described mech- 'anisrn are assembled the flanges I 'I are interposed between the rollers `I I and I Zand the anges 'I on -`respective slides 3, thus securing the slides `on their respectivefguides. `As shown in broken lines in Figui, the guides I5`may be swung around This `function is necessary in `0rdert`o adapt theseat for use in vehicles having only two doors`,to permit the seat to be swung' out of the jway of lback seat passengers.

A locking means is'"provided for `holding the Vslides `3against sliding movement relative to the guides I5. This locking `means is shown more particularly in Fig. 4 and comprises a bolt 26 slidably mounted in one of the slides 3 and having a locking portion 2'I adapted to project into one of a plurality of notches 28 in a flange I1 of 5 one of the guides, shown in Fig. 3. A flange I1 on the other guide I5 has a correspondingly spaced series of notches 29 (see Fig. 3) and a latch element 30 has a portion 3l adapted to project into these notches. The latch element 30 is secured on the end of a vrod 32 which is rotatably supported by a bracket 33. the rod having a handle portion 34 by means of which it may be manually moved. A link 35 is connected at one end to the bolt 26 and at itsY other end to the latch 30 by a slot and pin connection. designated at 36.

When the bolt 26 and the latch 30 are in engagement with one of their respective series of notches 28 and 29 the slides 3 are held against movement relative to the guides I5 andk when the rod 32 is moved rotatively by manual pressure they are withdrawn from theirrespective notches so as to leave the slides free to move on their guides, at which time the seat I may be moved forward orlrearward. With the parts in the position shown in Fig. 1, which is the extreme rearward position, further movement is prevented by the abutment 26, and with the parts in the position shownin Fig. 2, which. is the extreme forward position, further movement is prevented by engagement of the rollers I2 with the abutments I8. Duringmovement from the position shown in Fig. 1 to that shown in Fig. 2 the rollers II ride up the incline 23 Whereas the rollers I2 traverse the substantially horizontal path 22, resulting in an action wherein the seat fulcrums around the rollers I2.` This action tends to change the plane of the seat and to throw the back rest 2 forward into a more erect position. 40 The angularportions 8, 9 and IIJ of the flanges 'I remain in close proximity to or in light contact with the under surfaces of the flanges I'I during this movement as may be seen upon reference to Figs. 1 and 2. During movement from the posi- 45 tion shown in Fig. 1 the reverse action takes place, that is to say, the seat I fulcrums around the 'rollers I2 so that the rear edge is lowered and the forward edge lis elevated, while the back rest 2 is moved away froman erect position.

Although aspecic embodiment of the invention has been illustrated and described it will be understood that various changes may be made within the scope of the appended claims without departing from the spirit of the invention, 55 and such changes are contemplated. What I claim is:Y v y 1.` In combination, a pair of guides each having laterally projecting means at their upper `edges providing bearing surfaces which extend through- 60 out the length thereof, a pair of slides adapted for attachment to a vehicle seat and to be held thereby in parallel relation, rollers mounted in said slid'es and adapted to traverse said bearing surfaces, means on saidslides cooperating with 05 said laterally projecting means for maintaining said rollers ink rolling contact with said bearing surfaces, brackets at 'the fore and aft ends of said guides and adapted to be supported by a vehicle floor, said brackets being attached to re- 0 spective ends of said guides to support them spaced with respect to the floor, and an integral element on each aft bracket projecting above the bearing surfaces on said guides and into the path of movement of said rollers whereby engagement of the rollers therewith restricts movement of the slides with respect to said guides.

2. In combination, a pair of guides each having laterally projecting means at their upper edges providing bearing surfaces which extend throughout the length thereof, a pair of slides adapted for attachment to a vehicle seat and to be held thereby in parallel relation, rollers mounted in said slides and adapted to traverse .said bearing surfaces, means on said slides cooperating with said laterally projecting means for maintaining said rollers in rolling Contact with said bearing surfaces, brackets at the fore and aft ends of said guides and adapted to be supported by a vehicle floor, said brackets being attached to respective ends of said guides to support them spaced with respect tothe floor, an integral. element -on each aft bracket projecting above the bearing surfaces on said guides and into the path of movement of said rollers whereby engagement of the rollers Vtherewith restricts movement of the slides with respect to said guides, .said fore brackets being pivotally 'connectecl to ,their respective guide ends, and a rigid transverse member uniting said after brackets.

3. In combination, a pair ofguides, each guide being comprised of a lpair of angle pieces secured together in inverted opposed relation whereby angular parts-of each piece forms a complemental part of a bearing surface, said angle pieces having portions adjacent their ends spaced apart forthe reception of brackets, brackets'received between said spaced portions and attached to said angle pieces, the bracket atv one end of each guide having an integral portion projecting above said4 angle. pieces, and slides received on said bearing surface and adapted to be restricted as to movement thereon by' said projecting portions.

4. In combination, a pair of guides, each guide being comprised of a pair of angle pieces secured together in inverted opposed relation whereby angular parts of each piece forms a complemental part: of a bearing surface, said angle pieces having portions adjacent ltheir ends spaced apart forthe reception of brackets, brackets received between said spaced'portions, and attached to said angle pieces, the brackets at one end of each guide having an integral portion projecting above said angle pieces, the brackets at the other ends of said guides being pivotally attached to said angle pieces, and slides received on said bearing surface and adapted to be restricted as kto movement thereon by 4said projecting portions.

lthereon by saidv projection portions, and a rigid transversemember uniting the brackets having the projecting portions;
